Application led December 20,` 1918. Serial No. 267.669.

To all whom it may concern:

Be it known that I, Josnrn AsKiNs, a

citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented new and useful Improvements in Wrenches, of which the following is a specification.

The present invention relates to an improvement in wrenches and has for its object to produce an extremely simple construction of such devices, in which the movable jaw may be easily adjusted and readily locked in co-acting engagement with the stationary jaw. 1-

It is a further object of the invention to produce a wrench including a stationary jaw having a channeled handle anda movable jaw guided in the channel of the handle and designed to co-engage with the edges thereof and to be locked in such engagement,

whereby a quick adjustment between the jaws may be obtained and also whereby the movable jaw is not only guided by the han` dle of the stationaryjaw but firmly grips the same at different points so as to be reinforced thereby and firmly retained in engagement with an object.

It is a still further object of the invention to produce a quick acting wrench that shall be of an extremely simple construction, cheaply manufactured, easily operated, and thoroughly eflicient in its operation.

Other objects and advantages will appear as the nature of the invention is better understood, reference being had to the accom panying drawing, in which:

Figure 1 is a side elevation of a wrench constructed in accordance with the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view approximately on the line 44 of Fig. 1.

Fig. 5 is a sectional view approximately on the line 5 5 of Fig. 2.

Referring to the drawings in detail, the numeral 6 designates the stationary jaw of the wrench which has integrally formed therewith a right angularly disposed handle member 7. The handle member is U- shaped in cross section, being channeled from the inner face thereof throughout its length, and the sides8 of the said handle,

widened and have their edges provided with teeth 9. The handle 7, forthe length of the toothed portion 9 of the sides thereof has its upper face provided with a central slot 10.

The movable jaw is indicated by the nuv meral 11, the same having the sides of its active face widened as at 12 and the upper this shank is of a width approximately equal to the distance between the sides 8 of the handle 7. The shank 14 extends a suitable distance outwardly of the jaw proper having its rear face arranged at an angle or curvature with respect to the jaw, and the end of the said shank is curved upwardly as at 15, and the end of this upcurved portion is roundedso that the same will contact with the rounded connecting wall between the sides 8 of the handle 7. Integrally formed on the upper fiat face of the shank proper, directly above the threaded shoulders 13 is a threaded stud 16, and this stud passes through the elongated slot 10 of the handle and is engaged by a winged nut 19.

By adjusting the winged nut it will be seen that the jaw l1 may be readily moved longitudinally on the handle of the stationary jaw and quickly locked adjusted with respect to the said stationary jaw. The three points of contact between the movable jaw and the handle of the stationary jaw, that is, the engagement of the two shoulders 13 with the toothed surfaces 9 and the engagement of the rounded end 15 with the inner wall of the handle, affords a reinforcing engagement between the members of the wrench, pressing the jaw 11 so that the same will effectively engage with the article to be acted on. The shank being received in the handle and contacting with the sidewalls thereof holds the movable jaw against lateral or tilting movement, and it is thought, from the foregoing description, when taken in connection with the drawings that the advantages of construction and the simplicity thereof will be apparent without further detailed description.

Having thus described the invention, what is claimed as new, is

A wrench including a stationary aw having a cross sectionally U-shaped handle the side members of which having their outer edges toothed a determined distance and the back of the handle slotted for approximately the length of the teeth, .a movable jaw having a central shank received between the sidesvof the handle, widened portions on the outer sidesof the shank formed with teeth to (zo-engage with the teeth of the handle, said shank having a rounded end 10 which contacts with the rear' wall of the handle, a threaded stud on the inner face of the handle, and a binding nut on said stud. 15

In testimony whereof I ax my signature.

JOSEPH ASKINS.
